The equation 2/5d-1=3/5d-3 represents the number of dimes

d=10

Step-by-step explanation: step 1: 2/5d-1 = 3/5d-3           add 3 to both sides

                                                                   +3          +3

                                            step 2:  2/5d+2 = 3/5d subtract 2/5d to both sides

                                                         -2/5d       -2/5d

                                            step 3:         2 =  1/5d       multiply 5/1 to both sides

                                                              * 5/1 = *5/1

                                                                10 = d

step-by-step explanation:

.6 is 1/2 of 12

the answer is actually d. i just took the test

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
